Abstract (en)
[origin: EP0957445A2] A contact light emitting device comprises a transparent electrode layer (2) connected to an alternating current power source terminal, a luminescence layer (3) for generating a photo-image such as a surface pattern of a contact surface (10a) by an electric field and formed between the transparent electrode layer (2) and a contacted object (10) which acts as a ground, and a transparent insulating layer (1) for penetrating the photo-image and formed under the transparent electrode (2). <IMAGE>
